Thread: SR20 Turbo 02 Housing R&D

Let us know when you need one, they are hand made to order









Exactly...these are built to OEM GTiR or Bluebird/Avenir manifold and j-pipe fitment. You may have to fab parts if you mix and match components.

i might have missed, but do u make a T2 tubular manifold?

Nope, not yet...

So, I had this:

Engine W10 with JWT C1 cams
Manifold Avenir
GT2860RS with original 02 housing
3 inch downpipe all working together

Decided to change my manifold for the only turbo one I could found for my car and it's from a GTiR

So now I have
Engine W10 with JWT C1 cams
Autobann 88 GTir turbo header
GT2860RS with original o2 housing WHICH I want to change
3 inch downpipe

Here's my question again and hopefull it will be understood better

Which of the o2 housings you make will fit BETTER knowing I will still need to adapt my current 3" downpipe.

I, for sure, know that it's easier to cut some of the downpipe rather that to add to make it fit

2nd question

Which will perform better of the 2 and the 2 types GTiR or Avenir, Bellmouth or Screamer?

I want to get as much as heat out of of the head combustion chamber are with the best performance possible to get the most advantage of my coach potatoe and JWT C1 cams

Please answer me with the model you think it will be the better for Form Fit and Function on my car.

I really need to know what to order from you Javier.

Thank you


PD And I think my questions are the same ones the other have and want to be answered too.

why not just get a GTI-R manifold? they are very inexpensive and perform very well

I already have the turbo header and the measures distances are the same. But yes, if I had not gotten a chance to get this turbo header I would had gotten the GTI-R manifold.

Javier waiting for your answer

you could probably ship him the manifold and turbo and he could build on/around it

Yeah, He will start making one as soon as I buy one from somewhere else!

The GTiR j-pipe/housing will fit the manifold w/ GTiR stock turbo placement best, but you will have to modify the downpipe if it was built for a housing other than a GTiR.

Performance between both the Avenir/Bluebird and GTiR j-pipe design will be very similar if not identical. I recommend the divorced setup for weekend or track cars. Reason being, is that the divorced setup will be very loud! I also need the turbine housing that will be used to build the divorced housing. The divorced setups are hand matched to the turbine housing casting for the best possible seal.

The bellmouth is what I recommend for daily driven cars. It will seal 100% and will only be as loud as the rest of the exhaust. I don't need the housing for this j-pipe either.



Just let me know when you purchase the other manifold and I'll get started I won't be able to even think about designing a stock location GTiR manifold for another 2-3 months...it's on the back burner.

i have a PM of you saying that about 2 years ago!

anyways, are you still messing with the full 3" design?
